+# Multi-Company Employee Assignment (Odoo 19)
+
+This module extends the standard Odoo HR functionality to allow a single employee record to be associated with multiple branch companies.
+
+## Features
+- **Multi-Branch Assignment**: Add a "Branches" (Many2many) field to the employee form.
+- **Cross-Branch Visibility**: Employees appear in the "Employees" menu and search panel for all assigned branches.
+- **POS Integration**: Cashiers and employees appear in the POS login interface for all branches they are assigned to.
+- **Security Logic**: Access control rules are updated to allow visibility across all selected branches.
+- **Fallback Mode**: Existing employees with no branches assigned remain visible based on their original primary company.
+
+## Usage
+1. Open an **Employee** form.
+2. In the header/top section, find the **Branches** field.
+3. Select all the branch companies this employee should belong to.
+4. The first branch in the list will automatically be set as the "Primary Company" for standard Odoo processes.
+
+## Technical Details
+- Overrides `hr.employee`'s `company_id` to be a computed field based on `company_ids`.
+- Overrides `_search` and `ir.rule` to support Many2many company filtering.
+- Overrides `pos.config`'s `_employee_domain` for POS login visibility.
+- Includes transition logic for existing data.
